Crawl Space Encapsulation & Repair

As a homeowner in Charleston, you know that the area is no stranger to humidity and rain, but you may not realize how these common occurrences affect your crawl space. Most crawl spaces use wooden beams to support the floors of your home. When excess moisture infiltrates your crawl space, it can cause these beams to experience wood rot or mold – putting your entire home at risk. Additionally, moisture in your crawl space can lead to increased energy bills, damaged insulation, and pests.  

Despite these many problem signs, Mount Valley Foundation Services has the tools and expert knowledge to keep water out of your Charleston crawl space. Crawl space repair and encapsulation involves the installation of a dehumidifier, vapor barrier, support beams, sump pump, vent covers, and more to completely waterproof your crawl space. We’ve been helping homeowners in North Carolina and South Carolina keep their crawl spaces dry since 1986, and we’re ready to help you too!

Crawl Space Problem Signs in Charleston

As mentioned, excess moisture in your crawl space leads to many problem signs below your home, especially during the rainy and humid summers in Charleston. Wood rot and mold can form on wooden beams which causes them to break down over time. As the wooden beams break down, your home may suffer from sagging floors. Mold spores may spread into your home, causing potential health problems and more mold growth. High moisture can also lead to increased energy bills as humidity travels from your crawl space and into your living area. Furthermore, the Charleston humidity attracts all kinds of pests – from insects to rodents.

Causes of Crawl Space Damage in Charleston

Obviously, moisture is the main cause of crawl space damage in Charleston, but how exactly does so much water get below your home? First, open crawl space vents allow humid air to easily penetrate the crawl space. Ineffective vapor barriers might also cause more damage if installed improperly. Another issue is over spanned floor joists that occasionally occur during construction. Essentially, these are beams that are built too far apart and are unable to support the weight of your home. Understanding these causes is the first step in repairing them!

Crawl Space Solutions

Crawl space repair and encapsulation keeps your crawl space dry and supported with many different tools. When used in tandem, these solutions offer the most efficient defense against excess moisture that any foundation company can offer. Keep moisture out with a vapor barrier and dehumidifier. After a heavy summer storm, move groundwater away from your crawl space with our internal drainage system and sump pumps. Keep your floor joists supported with our steel crawl space support beams. The best part is – all of our solutions are designed to provide a permanent fix for your crawl space!

Absolutely love this company. From start to finish the sales rep and the people on the job were attentive to all of our needs. Originally we were meant to have our job done next week but they had an earlier slot and asked if we wanted it.We said yes and they sent two teams out to work on it. They were kind and efficient. Even after ripping up all the old plastic down there they cleaned every piece up and left no trace behind. We love our new crawl space door and the dehumidifier is quite.Within two day we could already see a difference in the humidity under the house.They let us know of a leak we had which i appreciate greatly.I recommend them to any and everyone. Best company we have found by far.

I received an inspection and estimation from Dino Rhoads on my house crawlspace today. I could not have asked for a more detailed inspection. Mr Rhoads was very professional, yet friendly. He explained everything in details. I thoroughly understand the entire process to be accomplished. Couldn't ask for a better representative from your company.

We have been very pleased with the service so far from Mountain Valley. We were in a difficult situation and needed the foundation work completed immediately. John Hickey was amazing and advocated for us and was able to get us scheduled soon. He has been a pleasure to work with and very professional. We will add more once the work is completed, but based on the interaction with this company so far we feel we will be more than pleased with the outcome.

The install team was amazing. They were patient and helpful with all my questions as well as did a great job with my encapsulation. I love that my crawl space is clean, neat and energy efficient now. Michael S., Sergio, and Nicholas A., were professional, and on-time. They worked hard and did a fabulous job. Now I would even go under my house if I needed to where I wouldn't have before.
